Since leaving rehab at the end of July, Lindsay has sworn off drinking and partying and moved from Los Angeles to New York.

However, earlier this month she was accused of ordering a friend to beat up socialite Barron Hilton at a party in Miami, although witnesses maintain she was sober at the party.

Journalist Lindsay MaHarry wrote: "Due to her probation, and the $2 million sobriety contract with Oprah [Winfrey], she was laying low, firmly on the wagon."

After leaving rehab, Oprah helped Lindsay turn her life around, and inked a deal for an eight-part documentary series about her post-rehab life for her OWN network, which reportedly includes a clause that Lindsay must remain clean and sober at all times.

Oprah has said of the star: "I believe that she believes that she is ready to move forward in her life. We'll see. I'm anxious to see whether or not this young woman ... will be able to allow us into her life and let us see the trajectory of trying to put the pieces back together."
